Application filed April 25, 1914. Serial No. 834,511.

To all whom t may concern.'

Be it known that l, CHARLES A. PATRICK, a citizen of the United States, residing at Hazel Dell,'in the county of Cumberland and State of Illinois, have invented certain new and useful Improvements in Ventilating Devices, of which the following is a specification.'

The object of my invention is to provide a Ventilating device or system adapted to be built or constructed in a boot, shoe, coat, article of Wearing apparel, toprovide` an insulation against sudden changes of 'temperature or extreme temperatures on the outside of the garments.

A further object isto construct a device of this character provided with circuitous or tortuous air passages so constructed that a free circulation of air is permitted.

With `other objects in view which will'be referred to, my invention consists in the peculiar combination and novel arrangement of parts, such as will be hereinafter more fully described in connection with the accompanying drawings and more particularly pointed out in the appended claims.

1n the draWings:-Figure 1 is a view in side elevation of a boot with my invention applied thereto and with parts in section to more clearly illustrate the adaptation. Fig. 2 is a fragmentary transverse sectional view on the line 2.2 of Fig. 1. Fig. 3 is a frag mentary vertical sectional view through the upper edge of the boot structure. Fig. 4 is a view in top plan of the disclosure in Fig. 1 with parts broken away at the foot to better illustrate the construction. Fig. 5 is a vertical sectional view through the sole structure. Fig. 6 is a view in side elevation of a slightly modified form which the upper end of the boot may take. Fig. 7 is an enlarged detail view of the structure disclosed in Fig. 6. Fig. 8 is a horizontal transverse sectional view on the line 8-8 of Fig. 7.

The boot as disclosed comprises the body portion l and the foot 2 which latter has the sole 3 secured thereto. To all intents and purposes these parts are in their outward appearance identical with the standard boot, but it will be seen as the description progresses that the body and foot must be slightly larger than the same parts of a boot of ordinary construction.

rl`he body portion of the boot comprises an outer covering 4f which is preferably waterproof or composed of rubber, to forni a protective covering, and to this outer layer el is `secured a corrugated filler 5 and a sub-- stantially non-elastic and preferably somewhat porous lining G is secured to the inner side ofthe corrugated filler 5. It will be understood that the outer covering 4 the corrugated filler 5 and the lining 6 are each flexible and are secured together in such a way that the finished garment will have sufiicient flexibility to give to the movement of the body of the wearer. In the body of the boot the corrugations of the filler 5 preferably extend in a vertical direction so that at the top edge they present their open ends, to close which ends the lining 6 is brought over the top edge of the boot structure and is secured down against the outer covering 4r and waterproofed to form substantially a part of vthis outer covering as at 7 and to form a reinforcing bead at this top edge.

In some instances the foot 2 of the boot can be made with the corrugations of the filler running in the same direction as the corrugations of the liller of the body 1, but it 1s perhaps preferable that these corrugations be made to run crosswise or transversely of the foot portion as better shown in Fig. 4f, where the filler S is applied to have the corrugations extending so that the openings formed between the filler and outer covering and the filler and the lining extend acrossI the toe and over the instep of the foot in a transverse direction and are open at their lower ends to cormnunicatewith the inner part of the boot near the sole. A plurality ofpassages 9 are formed throughthe corrugations of the filler 8 in a transverse direction so that communication is established between the outer and inner air cells and also between the air cells of the bodyportion 1 of the boot. v

The sole structure of the boot comprises the wearing surface 1'() which is formed as a continuation of the outer covering 4 or is cemented thereto to form a substantially one-piece structure,l and upon this 'outer sole 10 is placed a cushion sole 11 which cushion sole is made of rubber of a tough consistency or of other material which will withstand the bend of the sole incident to movement of the wearer, and on the upper surface of this cushion sole are a plurality of knobs or beads 12 of a resilient cushion material such as new live rubber and to give further resilience to this cushion'sole, means may be formed on the lower sid.

thereof to engage with the outer sole l0, ror additional cushion means may be disposed between the soles 10 and 11. An insole 13 of a flexible yet reasonably stiff material such as leather is provided to lit within the foot of the boot over the cushion sole 11 .and this insole is perforated throughout its- -to the upper side 'of the insole 13 and thus the air is permitted to circulate up through the foot of the boot and around the foot of the wearer.

The corrugated filler portion 5 is disposed y between the outer impervious covering 4 and the inner pervious lining 6, however, this filler strip is stopped slightly above the sole so that communication is established from the outer series of air passages to the inner series, and also 'the iller strip 5 is merged into the filler strip or sheet 8 so that communication ispermitted from the passages formed by the strip 5 to the passages or cells formed by the placing of the strip 8. Not only does this shortening of the strip 5 permit the flow of air from the outer cells to the inner cells, but also a clear passage is provided in this way to the cells of the sole structure, and in this connection it is preferable that the insole and other portions be notched at the edges as at 16, so that air passages are provided from the air cells of the filler strips 5 and 8 to the cells of the air space of the sole structure.

It is preferable that the free atmospheric air be permitted to have circulation through the cells of the filler 5 of the body portion 1 of the bootand in this way pass to the cells of the ller 8 of the foot portion and to allow the ingress of air' into these cells I have provided around the upper edge of the' body portion l of the boot just beneath the bead 7 a plurality of openings 17 through the outer covering 4 which openings permit the free access of air -between the outer cow ering et and the ller section 5l In some adaptations it may be found desirable to close. these openinllgs 17 or to regulate the amount of air whiph'can pass therethrough,

y and for this purpds'e I provide on the outer covering 4 a plurality of lugs 18 spaced a slight distance below the bead 7 at the upper edge of the boot, and a exible band of metal or other suitable material as indicated at 19 I `vis lprovided to fit around the body 1 of the boot between the lugs 18 and the bead 7 and to be held in place over the openings 17.

It will be understood that this band 19 is mounted to have sliding or turning motion 'around the body 1 of the boot over these openings 17 and a plurality of perforations 20 is provided through the band 19 so that when the band is turned to a certain predetermined position communication is established from the openings 17 to the atmosphere.

lVith the arrangement of the parts as dcscribed, so that the openings of the outer series of cells are at the top of the boot or garment structure and the communicating passages to the inner series of cells are around the sole or `in the lower part of the garment, the air will find itsway through the openings 17 and will fall ina'natural path down through the outer series of cells. The top of the boot is open and the heat generated by the foot of the wearer causes the air in the boot to become heated and to rise, this rising of the air from the lower portion of the boot acting to create suction through the outer series of air cells or passages formed by both the fillers 5 and 8, and thus fresh air is taken through the openings from the cells around the sole, part of the air thus being taken in being circulated through the sole structure and the remaining portions after receiving heat from the foot being caused to rise in a natural path up through the inner course or series of cells and to find its way through the inner pervious layer to exhaust through the top of the boot into the atmosphere. Air will be supplied through the outer course of cells of the leg portion of the boot to the outer cells of the foot portion when the parts are constructed as shown in Fig. 4, andthe circulation of the air from the cells formed by the filler 8 will be' in the same identical manner as the circulation is induced through the cells formed by the filler strip 5, and this circulation will be continued at all times by reason of the fact that heat is being constantly generated and thrown ol` by thc natural bodily warmth of the wearer and thus the circulation up through the top of the boot is continuous causing the circulation through the cells to be forced and maintained in a natural manner. Where the external condition of the atmosphere is cold,

this passage of the air down along the body of the boot, through the foot, and to the in terior thereof causes the air to become warm by contact with the parts of the boot receiving heat from the body of the wearer, and under reverse circumstances or where the atmospheric air is extremely'hot, this circulation tendsto cool the air passing ,through the cells of the boot and there is a consequent llgeduction of the air temperature within the oot.

While my invention has been described as applied to a boot, it will be understood that lsoy outer layer,

. strip and inner layer, provided with air passages adjacent to one 60 vious covering,

i naissant it is equally well adapted to use on shoes, stockings, coats, union garments, gloves and other articles of wearing apparel and that by arranging the cells between the inner and 5 outer layers and positioning the openings to the atmosphere in the manner described a free and constant circulation of air is ob- Ytained at all times. I

While I have herein shown anddescribed 1o 011e specific form which the' Ventilating device might take, it will be understood that slight changes might be made in the form and arrangement of the parts without departinof from the spirit and scope of my in- 15 vention, and hence I do not wish to be limited thereto except for such limitationsI as the claims may import.v
